the core sound engine in a series of products seldom changes,
only the software surrounding it is different
all of the sound producing potential of the V-Accordions
comes from one LSIC chipset, it is used in all models,
ALL the core acordion waveforms and the entire GM orchestra...
the chipset for FX is also the standard one Roland uses in all it's products
adjusting the software by manipulating the FX of a patch
or program can alter the sound you hear, but does not change
or add a new capability to the core of the device... the FX LSIC is
awesomely powerful, but you cannot access most of its's settings
from the device (the factory programmers can)
we actually took advantage of this by programming custom combinations
on an FR7x, using only location parameters available on an FR3x, then exporting
the fr7x patch and hacking it so it would load into the FR3x
in this manner, we were able to get the Percussive Voices from the
Orchestra LSIC to load, giving us a FR3x with Piano, Vibraphone, and Rhodes...
i gave this patch to Rose with permission to load it for select customers
(i had done this hack overnight when i was at Roxy's for en event where
we showed the new FR7x at the genessee music festival)
we were tipped off about this when we reverse engineered the Alpine
set, which interestingly had no Waveform data contained in it.
(meaning the Waveforms were already contained in the FR7x)
which was when i looked closer at the schematics and the light bulb went off !
SO ... the only actual diference in SOUND capability or improvement in the
V-Accordion series came when they added 4RAM memory locations to load 4 additional
sets of waveforms into the FR7x (and subsequent 8x/evo)
all other sounds from the beginning until now are derived from a common core
built in to EVERY model of V-Accordion
the only things that was actually different technologically in the X series
was a physically improved Keyboard (key action and response) and
the bellows sensor was doubled basically so a different set of data
was output on the pull vs the squeeze (which is what led to the
early issue of bellows imbalance and needed re-calibration in the field)
all other changes were in simple programming and cosmetics,
and marketing department hype
